CARTON-MAKING MACHINE.

Application led February 27, `1924. Serial No. 695,431.

To all fr0/wm t may concern.'

Be it known that I, HENRY F. SHAFFNER, a citizen of the United States,and resident of VVinston-Salem, in the .county of Forsyth and State ofNorth Carolina., have invented certain new and useful Improve ments inCarton-Making Machines, of which the following is a specification.

My invention relates generally to an attachment for a machine of thetype shown in the patent to Ludington, 561,332, for making paper cups orcartons for cigarettes, snuff, or the like, and is illustrated inconnection with a machine of this character although not limitedthereto.

1n the machine shown in the patent to' Ludington, a magazine isprovidedvwith a pluralty of blanks and a series of formers or mandrels arerota-ted step by step through four different positions in each of whichthey remain stationary for Aan interval. In the first position a blankis taken from the magazine, gummed appropriately and placed on theformer where it is held by a clip. The paper is also folded and the sideglued. The former then moves one-quarter of a revolution to the secondposition where the first folds of the end are made. other Vstep bringsthe former to the third position where the end is completed and thecarton is then fully formed. The final step to the fourth positionbrings the formerto a point where the Vfinished cup or carton isstripped off the former. The operation is then repeated. Of course whenthe machine is running, all four formers are in use and all stages areattained in sequence by each former. u

It has been found that this method of manufacture produced a cup orcarton the bottom of which lacked sufficient stiffness for properdurability in the filling and use of the same.

My invention relates to an attachment by which a piece of cardboard willbe placed in the bottom -of each cup formed as indi cated above andglued therein, thus impart# ing sufficient firmness and strength to thecompleted cup.

An object of the invention is to Vprovide an attachment of thischaracter which will be applicable to the machiner with very few changesand which will not interfere in 4any way with the operation of the otherinstrumentalities. i

.,Another object .is to` provide means for taking a card from the bottomofthe magazine and placingfit on the end of the former, where it is heldthroughout the lmanufacture of the cupV or carton.

Other objects will be apparent from the following detailed descriptionand the appendedA claims.

Power istransmitted to the shaft C from any suitable source and drives the is asection on tlhe line 7,-1-7 of 4' machine. A member D is given astep-by- Cil step rotary movement, and.: carries fourv ormers ormandrelsE. This member Dy stops momentarily at four points in itsrevolution sol asto bring each 'former successively into tour dil'erentpositions, two ot which are designatedin Figure 1 at ll and III. lVhenin the first positionhivhich, is diametrically opposite to position1LT., a

sheet of paper is takentronithe magazine .p

sition 11, the finished cupV isstrippedtroin the former, thus completingthe sequence orc operations. The operation thus.. fa-rv, describefd isor may besubstantiallythe same as that of the. Ludington patent, and thestructure ot' the machine is similar to that there disclosed.

Myinvention relates to an attachment tor placing a pasteboard bottom inthefcup or carton termed by the machine briefly de-n scribed above., ltinvolves only-'slight-modiication otl the trame, ot' the machine andkpractically no modification `of the mode of operation.

A shaft l driven in any, suitable manner carries a sprocket wheel 2about which passes Aa sprocket chain ,3 which passes about a sprocketwheel 4 on a shaft 5 supported in bearings in a bracket G on the frameotthe machine. An arm 7 on said shaft has a cam 8 pinned thereto by a riesa roller lO which works in a groove 1l in a cross head 12.

A bi'acketinember'13 (see Figure 13) has a lat portion overlying theshelf B to which it is t'astened by boltsyor screwspassing`throughiholes 15. lt also. has a doWnu-'ardly extending ledge portion'lprovided with bores 17 and ,18, as well as an arm 1S) Awhich has anoffset 2O at its lowr end provided with bores 21, 22 andv23. A stopscrew 24 is threaded through the member 13 Iand held in adjustedposition by a loclr nut 25.

Associated with the cross head 12 .and the bracket 13 are three rods `2627 and 2S. The rod 26 passes through thebores 17 and 21 and through abore in the cross head.l

lt is revoluble in said bores but is prevented from endwise movementrelative to the vcross head by` means ot collars 29 and.` 3.() fitting;above and below the cross head and fastened to the rod. V'llhe rod 26 isnormally held in one position by a spring 3l fastened at one end to apin A32 on the collar 29 and at its other end to a pin 33 on the crosshead.

As hereinafter.pointed out,Figure 5 represents an intermediate position vot' the parts.. The. rods26 and 27 act to operate mechanisintor stripping the finished carton orcup .'l'rom the tormer, and in themselves arenotnew.

The rod 28 slides through openingsltV and 23 anda bore vin the crosshead, but does not .receive its movement trom the cross head whichnierelyacts as a guide for said rod. livotally mounted `in a'braclret 42carried by the trame is .an angulanarmp43 having?. pivoted at 44 to itsend anupward extendingarm 45 whose upper. end is pivoted on a pin 46 inacut out 47 ofV a collan 48 that is fastV on the rod 28..., larried bythe arm 431is .a roller 49 with which con.-

tacts .the edge .ot the cam 8. i A ,collar 50` is carriedby the upperportion ot' the rod 28 and. limits its movement. A link 5l pivoted tothe arm 43 has a spring 52 connected thereto and the other .end of thespring is tast to a hook 53 carriedby the.

trame.

Each former has a central Vcylindrical bore ,in which slides a plunger54 whicn open at its upper endy and a spring ccntained within theplunger is fastened at one end thereto and at its other end to a pin5,6. Through one side oii theforiner a slot 5T communicates with thecylindrical boie and the plunger has an angular finger 5S attachedthereto and extending' through tliebore. `When theparts areiniiormalposition, shown for enamplein dotted linesy A at 82 to an arm 83 carriedby the shaft 74.A

ment of the former. As the cross head 12 and rods 26 and 27 movedownward from position X (Figure 2) to position Y the plunger 54 ispulled'down also and strips the completed cup olf the former. Atposition Y, the bloolr 40 engages member 20 and cannot move any farther.The rodV 26 continues to move and the finger 35 is calnmed to one sideby the cam groove 41, turning the rod 26 so that the lip 37 slips off ofthe finger 58 permitting the spring 55 to return the plunger' to normalposition within the former.

The rod 28 has a pin 59 at its upper end, and this pin engages andoperates mecha nism for feeding a lcard from the magazine to itsposition on the former. This will now be described. Y

Fitting in cut out 60 of the shelf B is a member 61 that is fastened tosaid shelf by bolts passing through holes 62 in the member andcooperating holes 63 in the a bearing fora certain operating sha-ft. It'

also has a groove 68 within which is placed the card feeding slidemechanism. l

The card magazine consists of a member fixed to the arm 65 and havingone open side, together with a removable container 69 of similar shapefitting therein and con-` taining the cards. A weight Q70 is placed uponthe cards, and the container has an ear 71 through which passes a screw72 which 'may engage or be threaded into the magah zine. proper 66. Thecards Z are of any desired size and thickness and are shownin Figure15..'

An upwardly extending bracket 73 supports one end of a shaft 74, theother end of which has bearing in an enlarged portion 7 5 of the side ofthe magazine 66." A shaft 76 mounted in the ears 67 has an arm 77provided at its end with an openslot- 78 in which engages the pin 59carried by the rod 28. Another arm 79 is carried 'by' the shaft 76 andhas a slot 80 therein in which works a pinat onel end of an adjustablelink 81 the other end of which is pivoted T he free end of the arm 83.isprovided with a slot 84 which cooperates with a pin 85 in the cardslide.

Two side pieces 86 fit within the channel 68 in the member 61 andattached to their ends are members 87 which are'also fastened torectangular rods 88 that are spaced from the members 86 to form guideslots 89. The card slide 90 has side extensions 91 which fit within theslots 89 so that the slide isguided in a right line. Ina depression inthe inner end of the card slide is mounted a movat one side of the card.

- Springs '97 surround these rods between the nuts and the slide, andthe tension of the springs can be adjusted b moving the nuts.v Thesesprings tend to holt the member 92 in its'depression in the slide 90'asshown in Figure 9. A downward projection 98 at the inner end of theslide acts as a stop for the return movement thereof. When the parts arein normal position as shown in Figures 1 and 3, the member 92 of theslide underlies the card magazine with the projections 93 slide broughtabout by a downward movement of the rod 28 acting through partsk 59 Amovement of the and 76 to 85 inclusive, causes the projections93 tocatch the lowermost card in the magazine land move it through the cutout side of the magazine toward the former. /Vhen it is in a positionclose to the former, the cup stripping plunger 54 is released by the lip37 and returns to normal rposition out of'the path of the card movingslide which is then moved underneath the former vby the further downwardmovement of the rod 28.

Referring particularly to Figure 6, it will be noted that the `member 92Vcarrying the cardis lifted in the following manner.v The card slide haspivoted thereto at 99 a lever 100'having a lower cam surface at 101 andoarriesa finger 102 which underlies the rod 94 and lwill raise they rodand member 92 when it is moved upwardly. An arm 103 is pivoted to theslide to swing freely, and this arm carries a roller 104 intermediateits ends and another roller 105 at its end. The roller 104 supports thelever 100 and cooperates with `the cam surface 101. The roller 105cooperates with a cam member 106 having an angular portion 107 fastenedby a screw bolt 108 to the member 61. As the card slide moves inward theroller 105 will 'spring' As soon as the roller .105
